The M145 Maserati GranTurismo is one of the most sensuous grand tourers ever. Today, I detail its mechanical and design variations over the 12-year production run.

Maserati Quattroporte V, tipo M139, is one of the most gorgeous sedans ever. Even over a decade after production ended, enthusiasts still flock to it. Today, I detail the changes in design and mechanicals over its 10-year production run.

Today, I compare the design of two German V12 biturbo engines, the Mercedes M279 and the BMW N74, along 7 aspects.

BMW’s N74 is the most technologically advanced V12 engine in a road car. BMW has kept it in production with exactly one technical update, the N74TU. Today, I briefly examine the changes made in the N74TU in five areas.

Some of Ferrari’s most collectible and unforgettable road cars are V12-powered grand tourers. Today, we look at the evolution of modern Ferrari two-seat GTs after the return of the front-engine V12 (berlinetta) layout over six generations.

Today, I compare the Mercedes S-Class and the BMW 7-Series over the last 6 or 7 generations from the matchup between W126 and E23, E32 to today's battle between W223 and G70.

Today, I briefly cover how GM’s Dynamic Fuel Management (DFM) system works. It should then be obvious why it is superior to conventional cylinder deactivation technologies.

Consumers commonly confuse the VAG EA824 and EA825 engines with each other. However, the Audi-designed EA824 and the Porsche-Audi EA825 are fundamentally different. Today, I compare the two across eight aspects.

Today, I briefly go over the mechanical and design evolutions of the Cadillac Escalade over its first five generations.

Today, I briefly go over the mechanical and design evolutions of the Porsche Cayenne over its first three generations. Emphases will be given to drivetrain and engine choice.

Today, we briefly examine the three main types of liner-less cylinder treatment methods that originated from Germany, Nikasil, Alusil, and Lokasil, and their variants.

Today, I compare the Mercedes-AMG M156 6.2L V8, the Maserati F136Y 4.7L V8, and the BMW S65B40 4.0L V8 across seven aspects. These engines use equivalent technologies but differ appreciably in their design goals.
